Answer:
Yes, they are correct.
Step-by-step explanation:
When reflected across the x-axis, the y coordinate changes. For example, (1, -1) becomes (1, 1). When translated left 5 units, it would be (-4, 1). Since that point is true, that means the shape is in its correct place.
Answer:
The area of the circle is 314mm²
Step-by-step explanation:
To solve this problem we have to use the formula for calculating the area of a circle
a = area
π = 3.14
r = radius
d = diameter
r = d/2
r = 20mm / 2
r = 10mm
a = π * r²
we replace the known values
a = 3.14 * (10mm)²
a = 3.14 * 100mm²
a = 314mm²
The area of the circle is 314mm²
Answer:
c = 75
Hope this helps!
Step-by-step explanation:
c + 38 = 113
c + 38 - 38 = 113 - 38
c = 113 - 38
c = 75
